Production of titanium zirconium molybdenum alloy head
According to its production method, Titanium Zirconium Molybdenum alloy head can be divided into three kinds: casting head, powder metallurgy head and processing shape head. The technological process is as follows. The main results are as follows: 1) the top of casting Titanium Zirconium Molybdenum is to melt the carbon-containing Molybdenum strip, pure titanium sheet and pure zirconium sheet into ingots through a true blank electric arc furnace. The vacuum is 133 × 400 Pa, the voltage is 30 × 32 V, the current density is 0.40 ≤ 0.45 A / mm ~ 2, and the melting rate is 0.8 ≤ 0.9 kg/min. The average service life of the head is 100 times. 2) Powder metallurgy. Titanium Zirconium Molybdenum top is to mix high purity Molybdenum powder, titanium hydrogenated powder, zirconium hydrogenated powder and carbon powder into rubber mold and press it at 150 MPa pressure. Then the compacts are sintered at 75% ≤ 80% melting point for 3? 5 h under hydrogen or vacuum conditions, and the density of the product is 9.3? 9.6g / cm. The average service life of the head is 300 times. 3) to process the variable form Titanium Zirconium Molybdenum head, the casting alloy ingot or powder metallurgy ingot is heated to 1300% for forging or extrusion deformation, which is called the machined variable form Titanium Zirconium Molybdenum head, which has an average life span of 400 times.
